See Template execution and order for details. Note that the execution order of looped line templates and looped syl/furi templates is different. Most Automation 4 Lua feature functions are passed a subtitles object when called. There is one special object (the subtitles user data object) which has a number of functions, and a number of table formats defined. Features include support for timing to both audio and video, and can use many video processing bindings to process those, such as FFmpeg and Avisynth. The program also supports other common formats such as SubRip. The number of loops must be a constant integer number, it can not be a variable or otherwise calculated dynamically. This page describes the subtitle file interface use in Automation 4 Lua scripts to manipulate subtitle files. Aegisubs native subtitle format is Advanced SubStation Alpha text, which supports subtitle positioning and styling. Tutorials: Introducing Karaoke Templater A simple example Using math expressions Using multiple. Karaoke Templater is already installed and ready to use along with Aegisub. Its primary purpose is to help creating karaoke effects with a specially designed template language. Specifying the number of loops is required. Karaoke Templater is an Automation script that ships with Aegisub. Specify that the template will be applied the given number of times. we don’t want a sword dropping down on a lone timed space, that just looks dumb. Also the noblank modifier is used to avoid producing anything for “invisible” syllables, eg. The template uses the notext modifier to avoid getting the original syllable text shown, because it’s being replaced with a vector drawing here. The effect itself is these small swords dropping down onto the syllables, by a move. The drawing is of a small simple sword pointing downwards. The first code line defines a vector drawing shape for convenience, so it doesn’t clutter up the actual template lines later on. “code once” lines are primarily intended to declare functions for use in templates. An easy way to create KFX (Karaoke Effects) and complex typesetting using the ASS format (Advanced Substation Alpha). They are run in the order they are declared. This class modifier is only valid for code lines.Ĭode lines with the once modifier are run exactly once during Karaoke Templater execution, and are always run before any other code lines or templates. Having one is still recommended for clarity, however.Ī template line without a class modifier is implicitly given the syl modifier.Ī code line without a class modifier is implicitly given the once modifier. Class declaring modifiers #īoth template lines and code lines can be produced without having a class modifier. There is a special set of modifiers that declare the class of the template line or code line. While modifiers can be combined to some extent, not all are compatible, and not all work on both code lines and for templates. This is a space-separated list of words in the Effect field following the template or code keyword. G - Commit: Copy the start and end times of the current audio selection into the line selected in the subtitles grid and move to the next line. Template lines and code lines can take a number of modifiers. A and F - Scroll Left and Right: Change the potion of the audio visible.
